Police responded to a reported robbery occurring at 532 Medford St. last Sunday evening.

The alleged victim, a driver for Green Cab in Somerville, reportedly told police that he had picked up a fare at Franklin and pearl Streets and proceeded to the passenger’s requested destination in Medford.

While on the way, the suspect reportedly asked the driver, “So, did you make a lot of money today?” The cabby said he told the man that he had not.

While the cab was stopped at a red light at Medford St. and Broadway, the passenger grabbed the driver’s neck from behind and demanded money, according to the alleged victim.

The driver refused to give the man any cash so he reportedly left on foot, heading into Medford, without paying the driver the fare he owed, according to the cabby.

Police units in the area were alerted and given a description of the suspect, who was soon found and placed into custody. The cab driver made a positive show-up identification and the suspect, Peter McCafferty, 51, of Medford, was taken to the police station and charged with unarmed robbery.

During booking, police dialed a phone number provided by the cab company that was reportedly from the phone that was used to order the cab in question. According to reports, McCafferty’s phone began ringing as it sat on the police station’s booking counter.
